Figure shows three transparent media of refractive indices `mu_1, mu_2 and mu_3`. A point object O is placed in the medium `mu_2`. If the entire medium on the right of the spherical surface has refractive index `mu_1`, the image forms at O'. If this entire medium has refractive index `mu_3` the image form at O''. In the situation shown

Options

A. the image forms between O' and O''
B. the image forms to the left of O'
C. the image forms to the right of O'
D. two images form one at O' and the other at O''

Answer

D
